Do you know what is Apple's worst kept secret? Its the new radical design for the headphone-jack-free iPhone 7. The best thing though is that it may become a reality if the leak a few days ago is true. But do the pictures show another potential design change?

The images come from self described "serial tech leaker" Steve Hemmerstoffer (who has a good record of accurate leaks), which appear to show a rear-facing plastic case for the iPhone 7.

While the pictures of a smartphone accessory isn’t exactly exciting news, the areas cut out for certain ports provides an insight into what to expect from the next flagship iPhone. Two things jump out to me immediately: there could be major changes to sound and battery size.

Several tech sites and blogs have been dedicated to Apple’s decision to ditch the headphone jack in favor using the lightning port. The lack of a headphone jack on this case further confirms that the age old connection is destined for the scrap heap.

The debate will rage on whether or not this is a good move for consumers. Do the pros of potentially better sound and a thinner phone outweigh the negatives of a painful transitional period, the initial limited amount of products with a lightning port connector (forcing people to buy new headphones or a proprietary convertor) and the issue of electrical waste? No, in my opinion.

Perhaps the unusually early nature of these leaks have forewarned headphone makers to prepare new designs for the world's most popular smartphone, which will neutralize some of the teething issues. But there’s no doubt that this will be an awkward sell.

The second thing that jumped out from the leak is that it looks like another set of speakers will occupy the abandoned headphone connector space.

This obviously means improved external audio, which perhaps is a way of bridging the headphone jack to lightning port transition.

What is a distinct possibility, however, is Apple scaling down its improved speaker technology in the iPad Pro and using it in the iPhone 7. The iPad Pro’s 4 self-balancing speaker drivers and resonance chambers give the Pro a more amplified sound (61 percent more than previous iPads according to Apple).
